Eaton swap in the works

[Ourobos]

I purchases a fairly complete Eaton swap yesterday. Over the next few months I hope to have it on my 03. I have a few questions, and will add to this thread as the questions grow, any help or insight is appreciated.

I plan on running the stock eaton 3.65" upper and a 2# lower, shooting for about 11psi. Will this be safe on my stock bottom end when properly tuned? Hoping it puts me right around 400 to the tires. Plans to build a bottom end and upgrade the blower in a few years are in the works.

Next, I purchased a new upgraded GT supercar pump. Can I go ahead and install this and will the car run properly with the added fuel? I'm used to return systems where the pump size doesn't really matter, the regulator sends the extra fuel on back to the tank. I'd like to be able to go ahead and get this in and drive it around the next month if need be while I'm prepping everything.

More to come, thanks again.

Reading through that should help. Any questions along the way post here. Lots of knowledgable folks on this board.

I am running a 3.4 and a 2lb lower at 11psi. I installed my fuel pump prior to doing my swap with no issues.

[Ourobos]

Excellent news 8UWITH6. Is you car pretty much stock otherwise, and what kind of power did that make on what type of dyno? I don't want to push this engine too far, but don't want to leave a lot on the table either.

Thanks

[8UWITH6]

No dyno. Butt dyno car feels 400 or less. Yes only other "mod" is deleted the rear cats. Car runs very well. I wouldn't push the stock engine too hard. I am already looking for a stronger short block.

[Ourobos]

Thinking of going with the stock 3.65" upper pulley I have, and a 4# lower. Does the metco 3.2" alternator pulley work on the Marauder application, and is it necessary or suggested like on the cobra?

[chief455]

Don't hurt your stock motor for a few ponies you'll never feel on the street..
Stock upper, 2# lower is a proven, long lasting, powerful combo.
Push the boost AFTER you swap in a forged motor and improved fuel supply

[Filby'sMarauder]

The alternator pulley is not necessary because you will have 2 belts, not 1 like the Cobra, to run everything. The supercharger has its own belt.

[Ourobos]

Thanks guys, again

[8UWITH6]

You have to remove the clutched pulley from the Marauder alternator. You have to buy a new pulley and nut from Ford.

[Ourobos]

Ahh.. From any particular vehicle, or have a part number 8UWITH6?

[martyo]

You have to remove the clutched pulley from the Marauder alternator. You have to buy a new pulley and nut from Ford.

I believe that the pulley was discontinued by Ford.

I had come pulleys made up and ordered the nuts for inventory for that reason.

[8UWITH6]

Alternator pulley f5az-10344-a Motorcraft gp-712. Nit sure on the nut. I'm certain you can google this information if need be.

[guspech750]

I bought the nut from a hardware store. Still works.

Stuck with stock Eaton pulley and 2# lower until I can beef up the bottom end, rear end, and 4r70w in the next year or so. Hope to have it on the road in January.

[Ourobos]

Getting this improved Ford GT pump in right now.. Fun reaching these wires.. Yeah buddy

[Ourobos]

And of course now my gas gauge is way off.. Is there a baffle in these tanks the arm could be caught on? Seemed like a simple drop right back in procedure. Oh well, can't live with that crap, back out to pull it again.

[Ourobos]

Some dummy put the sending unit on upside down when reinstalling it LOL.. gauge is good, pump is good.. Good day today

At least you spotted the issue before continuing. Good work sir.

[Ourobos]

Is the stock 03 Cobra airbox compatible with the Marauder, is there a spot in the fender apron to pull air in? I'd prefer not to get a filter and adapter flange yet, unless necessary.

[8UWITH6]

Just buy a conical K&N and be done with it in my opinion.

[Ourobos]

Yeah, another $90.. Not a deal breaker, but I have the stock piece and only running 10 psi. I plan on a conical when I upgrade the engine in a year or two, but can I get by with the stock piece ;)

[justbob]

I've found the Spectre cheap brand to be a great filter. Not only is it an open front unlike the K&N but it's also a stock item at Advance for only $20.

Still cleanable as the rest but at that price I just buy a new one every year.

Went ahead and spend the $60 and got the flange and filter :

[Ourobos]

So a day after the improved GT supercar pump, I'm pulling a P0190.. I'm reading because there's more pressure at the sensor than it's parameters, and to have the tuner up the range when it's tuned, sound right? Runs great. It does take a half second longer to start when cranking than it did with the stock pump, but I'm pretty keen on changes, nothing REAL noticeable.

[loud2004marquis]

Had the same fuel pump installed a few months before doing the Eaton Swap on mine and didn't have any codes.

[Ourobos]

Odd.. I can't imagine my fuel pressure sensor just happened to go out the same time I upgraded the fuel pump. I suppose I'll have the tuner check the values when I get it there to be sure. Thanks for the input

[Ourobos]

Received my Autometer vacuum/boost gauge, Autometer oil gauge, and my ring set to make my volt meter my 3rd gauge today. May do some work this weekend and get em installed. Will put up before and after pics if so.

[Ourobos]

Well my P0190 keeps returning. Mind you this is an immaculately maintained car, never any issues. This came up the DAY after the fuel pump upgrade. Any other theories before I waste $100 on a new sensor.

It's the fuel pump voltage tables.

[Ourobos]

Thanks Zack, I think it was your thread I searched and read that, that's where I got the idea. I'll just leave the CEL on and let the tuner handle it when I get there. I appreciate it.

[8UWITH6]

No worries keep driving.

[Ourobos]

You guys rock..

[Ourobos]

No real updates on the swap. It's in the shop in the works. Maybe 2-3 weeks away, I'm pretty busy with work. I do have a dyno appointment 1-22-16, so definitely by then.

In the meantime, I am building a shortblock for next year when I decide to upgrade the blower, rearend, transmission, etc.

I have a Cobra crank, 4340 H-beams, and these nice Wiseco babies that just got here today.. Pieces of art :

[Ourobos]

Disassembly has begun

[Turbov6Bryan]

Looks like tons of fun!

Git r dun

[8UWITH6]

Post questions here or PM. Doing it in 4 days? ;)

[Ourobos]

LOL, if it weren't for all these FAMILY get togethers I would.. ;)

[Filby'sMarauder]

Good luck with your build. I'm sending you a PM.

[Ourobos]

Making progress. Had an 8 rib alternator pulley by mistake, had to order a 6-rib, will be here next week. Still making some progress. Coolant crossover cut and welded, blower on, never cam covers on, brackets mocked up.. Won't be too long now

[Ourobos]

For those interested on seeing the crossover modifed..

Before, during and after

[8UWITH6]

Oh the infamous crossover tube...........

[Ourobos]

It certainly took some fabrication

[lji372]

It certainly took some fabrication

Meh cut some pipe weld it together, no biggie :lol: j/k

[Ourobos]

Well it wasn't like building the Taj Mahal, but it did take quite a few cuts

[Zack]

I hope you pressure tested it.
Welding that close to the factory bungs (which are brazed in) will cause the brazing to become liquid and leak out.....causing a LOT of leaks

[Ourobos]

I indeed did. Thanks for the heads up.

[Ourobos]

Waiting on this dang alternator pulley

[8UWITH6]

Do explain the coolant reservoir and its purpose. Engine or blower supply? I have never seen one like that.

[Ourobos]

Intercooler tank.. I think it came from a Lightning, you're right, doesn't look like a Cobra.

[8UWITH6]

Makes sense. My Dad has an 03 Harley F150 looked familiar.

[Ourobos]

Headed into the home stretch. Put the startup tune on it. Have to test drive, if all is well, dyno tune on 1-22.

[Drewstang]

Needs more burnout videos.

[ChiTownMaraud3r]

This reservoir setup looks better imo. More factory looking as my car has a gap in that position now.

[Ourobos]

I like it as well. It's a Lightning / Harley F150. I guess the only draw back is you MUST run a shorter conical filter. No problem there though. I'll post up numbers after the dyno on 1-22. It's a Mustang Dyno, hoping for 375rwhp. This is bone stock with 10 psi and mufflers only (rear cats deleted). Anything higher is just a plus.

I will laugh when it does over 4 at the tire. Keep us posted.

[Ourobos]

I will too, I'd be tickled.. Will do

[justbob]

I suspect you'll see at least 410 on a Mustang. Years ago I made 445/431 on a dynojet with only mufflers, a 3.2, conical air filter/lightning MAF/MAFia & stock zip tube running 11.7#s. This was with the auto trans and everything else bone stock.

Awesome! another eaton swap completed!

[Drewstang]

Any numbers or did you get caught in the Snowpocalypse?

[Ourobos]

Snow.. Schedules in 3 weeks now

[Ourobos]

Where to tap into for boost gauge? I have no small vacuum tubes or port on this Eaton or near it. Just the ~3/8" that feeds everything. EGR has been deleted. Any ideas?

[8UWITH6]

I think I reduced the lowest 3/8" port down with a tee for 7/32 and 1/8 for the boost bypass valve and the fuel rail pressure sensor. Then tee'd into the 1/8 line going to the fuel rail pressure sensor for the boost gauge. Hell I would I have to go look at it.

[justbob]

What did you do with the MAP sensor hole or did you use that for your IAT? I've tapped them in the past and used that because I chose a regular IAT 3/8" sensor elsewhere.


Sent from my iThrone using Tapatalk

[Ourobos]

Got rid of MAP for IAT..

I just hate to have so many Tee fittings, I'll look into tapping into the boost bypass valve.

Thanks

[Ourobos]

Converted my center gauge cluster to a 3-gauge setup today. Put the boost gauge on the driver's side, a real Autometer oil gauge in the center, and left the volt gauge on the right. I might go with a trans. temp gauge instead of volts eventually. Also of note, I had to drill through the firewall for the boost gauge tubing, I saw nowhere to run the line otherwise. I also used LEDs on all the gauges. I'm super happy with it. I got to see a brief 10psi as well. Still waiting to tune on 2-25 to fully utilize the boost function ;)

[MOTOWN]

There's a few openings you could have routed the boost/vacuum tubing through, no need to drill the firewall , i hope you used a quality grommet or you will be tracing a vacuum leak in the future.

[Ourobos]

Hah indeed. I couldn't find one near the driver side at all, and the passenger side was full of HVAC. Where is a good one for future reference ?

[MOTOWN]

The easiest way is to slot an existing factory grommet, and route it that way there's quite a few on the drivers side.

[justbob]

Above the gas pedal is the one I use. Small incision on '03's, or run the tubing right thru the brake release vacuum line (same grommet) on '04's as they don't use it. Both ends are just capped off.

I put a JLT oil separator on last week in case of any blow by. Just check it for the heck of it, and it had about 1/2" of some light brown transparent water in it. What's up with that. Not a drop of oil in it. Almost had a fuel smell, but tasted like water ;)

[Marauderjack]

Water vapor pulled from the crankcase......not unusual especially in cold weather!!:shake:

[8UWITH6]

Makes me feel better. Friday in the shop I was bench racing (drinking beer) with Turbov6Bryan and Jaydees and I pulled my catch can out for fun. It was 3/4 full of water and of course the light brown oil. I was a little worried about the water but it has been about 3000 since I changed the oil. Amazing how much moisture it pulled out!

[Ourobos]

Finishing up at Blankenship Tuning, at 16 degrees timing, on 10.5 psi, the Marauder made 392 rwhp, and 406 torque. Mustang Dynamometer :) Quite satisfied.

[8UWITH6]

Nicely done.

[2,4shofast]

Nice numbers, I would be happy with that.:beer:

Every since my swap and flipping the alternator, although it works great, it is making a squealing noise, mainly at 2500 rpm and above. A quick shot of silicone spray on the pulley shaft stops it for a day or two, then it's back. Is this due to turning CCW now? Any easy solutions other than replacement?

[myrodr]

Check the belt length. Mine was at the end of travel for the belt tensioner ,shorter belt fixed the problem for me.

[Ourobos]

Will do. Wondering why a little lube on the alt. shaft stops it though?

The spacing is not correct.
Try moving it away from the timing cover by adding 1 washer on each mounting stud.

Been there, done that

[Ourobos]

Excellent, thanks.

[8UWITH6]

I am lazy, I just put a dab of dielectric on the belt. Maybe I should try the washer thingy.

[Ourobos]

Lil' dab did the trick til I can get it in the shop next week or so and put the spacers in.. Thanks for the tip, dielectrics lasts a lot longer than silicone spray.

[silversnake]

Agree with spacing not being correct. I had the same issue. I had the wrong alt. Pulley which caused belt alignment to be slightly off. Replaced my pulley with the correct one and never squeaked again
